Abstract

La présente invention concerne une conduite pour le transport de gaz, notamment de dioxyde de carbone, comprenant au moins un élément tubulaire, l’élément tubulaire (1) étant formée par une juxtaposition de couches concentriques comprenant, en allant de l’intérieur vers l’extérieur, au moins une couche d’étanchéité (5), une paroi comportant une couche en béton précontraint (6) et au moins une couche de renfort mécanique circonférentiel (8). De plus, le béton composant la couche en béton précontraint (6) est choisi parmi les bétons fibrés à ultra haute performance (BFUP) et la conduite est configurée (dimensionnée) pour résister à une pression supérieure à 70 bar (7 MPa).
